I was wondering if anyone had any idea what's happening here. I have an Asus N53SN laptop running Windows 7 which has an Atheros Azurewave WLAN/Blutooth card installed. I've never had a problem with it for the two years that I've owned it. A couple weeks ago the wifi signal suddenly started dropping out for no reason. First my home router signal would disappear, cutting me off from the internet, then the list of other wifi hotspot signals would dwindle down to about 4 (from like a dozen), and then none at all. The wifi icon would show a red x through it. It was, however, not disabled nor turned off. The Wifi switch on the side of the laptop is on and pressing FN + F2 confirmed it. I downloaded the latest drivers and that seemed to help, but not for long. Eventually it would fail again and not sense any hotspots. Over the past two weeks I've found the behaviour to be extremely erratic. I thought it might be a virus but scans found nothing and I also found no similar issues online to match my problem. When this first happened, my initial reaction was to do a system restore to an earlier point, but that too was only a temporary fix. It keeps happening. I also disabled the Windows Firewall and automatic power management options for the wireless device.
So then I figured there might be something physically wrong with the card. So I took the laptop apart and inspected the card. Nothing visually wrong with it. The antennae are also firmly connected to the card and there doesn't seem to be any damage to them (one is bluetooth, which I've never never tried because I have no bluetooth devices). So I put it back together and started it up. Works again. But not for long. The working behaviour can last anywhere from 2 minutes to 2 days without interruption. It's becoming extremely annoying and I must find the answer.
The only difference to my system before this problem started was installing a couple new Steam games, I believe. I never installed any new software or anything. And restoring to an earlier point obviously didn't help anything so it can't be a software issue. Could my wireless card simply have died? Any ideas that I may not have tried? Whenever this issue crops up again I just have to keep switching the wifi device on and off, disabling and enabling, or uninstalling and reinstalling (including old drivers and new drivers) until it randomly starts working. But if I do nothing and just leave it, it never comes back on its own. I always have to do something. My router is not the issue because all my other wifi devices in the house work just fine. And if my router was the issue, I'd still be able to scan other hotspots which it doesn't do when this issue starts. Any help would be appreciated. I'm at my wit's end.
